Description

Technical Field

[0001] This utility model belongs to the field of electrical connection suspension operation technology, and in particular relates to a suspension detection device and suspension detection equipment. Background Technology

[0002] In the infrastructure inspection industry, there are many scenarios involving suspended electrical connections, most of which involve the inspection of buildings and facilities. Because manually performing these suspended electrical connection operations poses significant safety hazards and incurs high labor costs, most such operations are now accomplished using suspended devices such as drones.

[0003] However, some electrical connection operations that require contact operations to obtain information are not possible, such as grounding detection. Because the surface shape of the structural components to be tested is not uniform, it can usually only be detected remotely or by manual climbing. If electrical connection detection is performed using suspended detection equipment, the detection probe of the suspended detection equipment will have a hard collision with the structural component to be tested, which can easily disrupt the stable and normal operation of the suspended detection equipment and even lead to the risk of the machine exploding. Utility Model Content

[0004] The purpose of this utility model is to provide a suspension detection device and suspension detection equipment, which aims to solve the technical problem that current electrical connection suspension contact operations cannot be completed by suspension detection equipment.

[0006] The probe assembly includes multiple detection probes that are capable of making electrical contact with the surface to be tested of the structure under test when they come into contact with the structure under test.

[0007] An adaptive mechanism is connected to the detection probe and to the suspension device. The adaptive mechanism can adaptively deform flexibly to change the state of the detection probe so that the end of the detection probe can contact the surface to be inspected with different shapes and achieve electrical connection with the surface to be inspected. It can also buffer the force on the detection probe at the moment of contact.

[0008] In one embodiment of the first aspect, the adaptive mechanism includes a detection circuit board, an adaptive seat, a first adaptive element, a second adaptive element, and a fixed seat. The detection circuit board is connected to the adaptive seat, and a plurality of detection probes are electrically connected to the detection circuit board. The fixed seat is connected to the suspension device. The first adaptive element includes a first end wall, a second end wall, and a flexible side wall connected between the first end wall and the second end wall and capable of flexible deformation. The first end wall and the second end wall are respectively connected to the adaptive seat and the fixed seat. The first end wall, the second end wall, and the flexible side wall enclose a sealed cavity for accommodating fluid. The adaptive seat is provided with a limiting structure. The second adaptive element is elastically connected between the base of the detection probe and the adaptive seat, so that the end of the detection probe can conform to the surface to be inspected in the detection state and maintain its initial state before and after detection to adapt to different surfaces to be inspected. The detection probe is movably connected to the limiting structure, so that the state of the detection probe is kept within the range allowed by the elastic deformation of the second adaptive element.

[0009] In one embodiment of the first aspect, the adaptive seat includes a first adaptive member and a second adaptive shell connected to each other, the first adaptive member being connected to the second adaptive shell, the limiting structure being disposed on the first adaptive member, and the detection probe including a rod portion and a detection portion elastically connected, the rod portion being connected to the second adaptive shell.

[0010] In one embodiment of the first aspect, the limiting structure includes a connection hole formed on the first adaptive member, and each of the detection probes is movably connected to one of the connection holes.

[0011] In one embodiment of the first aspect, the adaptive seat has a detection surface, the detection probe protrudes from the detection surface, and the adaptive mechanism further includes at least one limiting block connected to the adaptive seat and protruding from the detection surface. The height of the limiting block protruding from the detection surface is less than the height of the detection probe protruding from the detection surface. When there are multiple limiting blocks, the multiple limiting blocks are arranged sequentially along the circumference of the probe assembly.

[0012] In one embodiment of the first aspect, the limiting block further includes a buffer pad for contacting the surface to be inspected.

[0013] In one embodiment of the first aspect, the first adaptive member is provided in multiple ways, and the adaptive mechanism further includes multiple detection members connected to the fixed base, each of the detection members being used to detect the pressure parameter and / or pose parameter of at least one of the first adaptive members.

[0014] In one embodiment of the first aspect, the suspension detection device further includes a connecting rod, an electrical control box, and an adjustment mechanism. The electrical control box is used to connect the suspension device, the connecting rod is connected between the adaptive mechanism and the electrical control box, the electrical control box is communicatively connected to the detection circuit board, and is used to control the probe assembly to perform detection. The adjustment mechanism is connected between the electrical control box and the suspension device, and is communicatively connected to the electrical control box. The adjustment mechanism is used to adjust the position of the connecting rod.

[0015] In one embodiment of the first aspect, the suspension detection device further includes a vision module connected to the connecting rod, the vision module being used to acquire image information near the probe assembly.

[0016] Secondly, a suspension detection device is provided, including a suspension device and the suspension detection device described in the above embodiments. The suspension detection device is connected to the suspension device, and the adaptive mechanism can also buffer the force transmitted to the suspension device through the suspension detection device during the contact detection process. The suspension device is an aircraft.

[0017] The technical advantages of this invention compared to existing technologies are as follows: The suspended detection device of this application incorporates an adaptive mechanism between the detection probe and the suspended device. At the instant the detection probe of the suspended device contacts the structural component under test, the force exerted by the structural component on the detection probe is transmitted to the adaptive mechanism, causing it to undergo adaptive flexible deformation. This achieves electrical connection with the surface to be inspected on the structural component. Simultaneously, the detection probe can also be buffered by the adaptive mechanism, ensuring flexible contact between the detection probe and the structural component, effectively preventing hard collisions between the suspended detection device and the structural component, guaranteeing stable operation of the suspended device, and reducing the risk of device failure. Multiple detection probes can adapt to different shapes of surfaces under test through the flexible deformation of this adaptive mechanism, thereby achieving stable electrical contact with various structural components under test.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Please see Figure 1 This embodiment provides a suspended detection device 100, which is used for electrically connected suspended operations. In use, it is generally connected to a suspended device 200 to cooperate with it. When an electrically connected suspended operation is required, the suspended device 200 drives the suspended detection device 100 to the detection position. The suspended detection device 100 can then make electrical contact with the structural component under test at the detection position to collect and detect information about the component. The suspended device 200 includes, but is not limited to, drones or other aircraft, or devices that perform suspended operations such as booms or suspended baskets.

[0031] The structural components under test include, but are not limited to, lightning arresters installed on the blades of wind turbines. Wind turbines operate in open environments, and the tips of the blades, which are at their highest point during operation, are susceptible to lightning strikes. Therefore, wind turbines are generally equipped with a wind turbine blade lightning protection system, which can effectively absorb lightning energy and prevent damage to the turbine. The wind turbine blade lightning protection system includes a lightning arrester. The suspended detection device 100 can be transported to the lightning arrester via a suspension device 200 and electrically connected to the lightning arrester to check whether the grounding of the lightning arrester is normal. In this way, the suspended detection device 100 can replace remote detection and manual climbing inspection, improving the efficiency of wind turbine blade lightning protection grounding testing. The surface to be tested by the lightning arrester can be a vertical surface, i.e., a surface perpendicular to the ground or at an angle to the horizontal plane. The suspended detection device 100 needs to contact this surface to achieve electrical connection with the lightning arrester. The shape of this surface to be tested may vary in different models of wind turbines.

[0032] Please see Figure 1 This application also discloses a hovering detection device, which includes a hovering device and the aforementioned hovering detection device 100. The hovering device is the aforementioned UAV, used to perform flight operations. The hovering detection device 100 is connected to the hovering device.

[0033] The suspended detection device 100 includes a probe assembly 10 and an adaptive mechanism 20. The probe assembly 10 is used for electrical contact with the surface to be inspected of the lightning arrester, and the adaptive mechanism 20 is used to adapt the probe assembly 10 to the surface to be inspected of the lightning arrester through deformation. The adaptive mechanism 20 can buffer the force transmitted to the suspended device 200 through the suspended detection device 100 during the contact detection process.

[0034] Please see Figure 2 and Figure 3 The probe assembly 10 includes a plurality of detection probes 11, which are rod-shaped. The detection probes 11 are able to make electrical contact with the surface to be inspected of the structure under test when they contact the structure under test. Specifically, the detection probes 11 make contact with the surface to be inspected of the structure under test through their ends to achieve electrical connection with the structure under test.

[0035] An adaptive mechanism 20 is connected to the detection probe 11 and is used to connect to the suspension device 200. The adaptive mechanism 20 can be directly connected to the suspension device 200 or indirectly connected to it through other structural components. The adaptive mechanism 20 can adaptively and flexibly deform to change the state of the detection probe 11, allowing the tip of the detection probe 11 to contact surfaces of different shapes and achieve electrical connection with the surface. It can also buffer the force applied to the detection probe 11 at the moment of contact. The aforementioned adaptive flexible deformation refers to flexible deformation that allows the detection probe 11 to adapt to the lightning arrester. The flexible deformation methods include at least one of extension deformation, bending deformation, and torsional deformation. Changing the state of the detection probe 11 includes, but is not limited to, changing the extension length, angle, and degree of bending of the detection probe 11.

[0036] The suspended detection device 100 of this application uses an adaptive mechanism 20 between the detection probe 11 and the UAV. At the instant the detection probe 11 of the suspended detection device 100 carried by the UAV contacts the surface to be inspected by the lightning rod, the force exerted on the detection probe 11 by the surface to be inspected is transmitted to the adaptive mechanism 20, causing the adaptive mechanism 20 to undergo adaptive flexible deformation. This achieves electrical connection with the surface to be inspected. Simultaneously, the detection probe 11 can also be buffered by the adaptive mechanism 20, allowing for flexible contact between the detection probe 11 and the surface to be inspected by the lightning rod, effectively avoiding hard collisions between the suspended detection device 100 and the lightning rod, ensuring the stable operation of the suspended device 200, and reducing the risk of the suspended detection equipment crashing. Multiple detection probes 11 can adapt to different shapes of surfaces to be inspected through the flexible deformation of the adaptive mechanism 20, thereby achieving stable electrical connection with various structural components under test.

[0037] In some embodiments, please refer to Figure 3 and Figure 4 The adaptive mechanism 20 includes a detection circuit board 21, an adaptive base 22, a first adaptive element 23, a second adaptive element, and a fixed base 24. The fixed base 24 is connected to the suspension device 200, wherein the fixed base 24 can be directly connected to the suspension device 200 or indirectly connected to the suspension device 200 through other structural components. The two ends of the first adaptive element 23 are respectively connected to the adaptive base 22 and the fixed base 24. The detection circuit board 21 is connected to the adaptive base 22, and multiple detection probes 11 are electrically connected to the detection circuit board 21. The second adaptive element is elastically connected between the base of the detection probe 11 and the adaptive base 22.

[0038] The first adaptive member 23 is capable of telescopic and torsional deformation. It also has a sealed cavity filled with fluid to absorb impact forces, thus achieving a buffering effect. Specifically, the first adaptive member 23 includes a first end wall, a second end wall, and a flexible side wall connecting the first and second end walls and capable of flexible deformation. The first and second end walls are respectively connected to the adaptive seat 22 and the fixed seat 24. The first end wall, the second end wall, and the flexible side wall enclose a sealed cavity for containing the fluid. The fluid in the sealed cavity can be, but is not limited to, gas or liquid. Understandably, the first adaptive member 23 can be a structure such as an airbag capable of stretching and shortening.

[0039] The second adaptive element is elastically connected between the base of the detection probe 11 and the adaptive seat 22, so that the end of the detection probe 11 can fit the surface to be inspected in the detection state and maintain the initial state before and after the detection to adapt to different surfaces to be inspected. That is to say, the detection probe 11 maintains the initial state before the detection, and the state can change during the detection process, such as through the elastic expansion and contraction deformation, elastic torsional deformation or elastic bending deformation of the second adaptive element relative to the adaptive seat 22, or through its own elastic expansion and contraction deformation, elastic torsional deformation or elastic bending deformation, etc. After the detection, it can return to the initial state for the next detection. In this way, the probe assembly 10 can adapt to the surface to be inspected with different shapes.

[0040] The second adaptive component and the adaptive seat 22 can be fixedly connected or movably connected. The movable connection can be one or both of rotational connection and sliding connection.

[0041] The adaptive seat 22 is provided with a limiting structure 22a, and the detection probe 11 is movably connected to the limiting structure 22a, so that the state of the detection probe 11 is kept within the allowable range of the flexible deformation of the second adaptive member. The limiting structure 22a restricts the range of motion of the detection probe 11. The movable connection between the detection probe 11 and the limiting structure 22a may include one or both of rotational connection and sliding connection. Among them, the rotational connection can be rotation about an axis or universal rotation.

[0042] During operation, when the probe assembly 10 transmits the force of the lightning arrester to the first adaptive member 23 and causes the flexible sidewall to deform flexibly, the fluid flows in the sealed cavity to absorb part of the external force of the first adaptive member 23, thereby achieving a buffering function. That is, the reaction force generated by the lightning arrester on the detection probe 11 will not be completely transmitted to the suspension device 200. Furthermore, by causing the flexible sidewall to deform flexibly, the state of the detection probe 11 can be adaptively adjusted, thereby achieving state adjustment of the detection probe 11 relative to the lightning arrester. This ensures that the multiple detection probes 11 in the detection assembly maintain effective electrical contact with the surface to be inspected of the lightning arrester.

[0043] Optionally, the flexible sidewall can be corrugated, and when no force is applied, the first adaptive element 23 extends in a straight line, with its central axis perpendicular to the detection surface 2211.

[0044] Optionally, the detection probe 11 includes a rod 111 and a detection part 112. The detection part 112 is slidably connected to the rod 111, and the direction from the detection part 112 to the rod 111 is the extension direction of the detection probe 11. The detection part 112 can slide along the extension direction of the detection probe 11. The end of the rod 111 facing away from the detection part 112 is electrically connected to the detection circuit board 21. The detection circuit board 21 is fixedly connected to the adaptive seat 22. The second adaptive element is connected to the detection circuit board 21 and is connected to the adaptive seat 22 through the detection circuit board 21. The detection part 112 and the rod 111 achieve telescopic deformation through the second adaptive element. In the initial state, the second adaptive element can apply an elastic force to the detection part 112 that slides away from the rod 111, so that the length of the detection probe 11 remains at its initial length. The end of the detection part 112 facing away from the rod 111 is the end of the detection probe 11. When the end of the detection probe 11 abuts against the surface to be tested of the lightning arrester, the detection part 112 slides toward the rod part 111, the second adaptive member is compressed and deformed, and the length of the detection probe 11 decreases. After the detection probe 11 separates from the lightning arrester, the detection part 112 slides away from the rod part 111 under the elastic force of the second adaptive member, so that the detection probe 11 returns to its initial length, that is, the detection probe 11 returns to its initial state.

[0045] The second adaptive element can be a spring, which is sleeved inside the rod portion 111 and connected to the detection portion 112. In other embodiments, the second adaptive element can also be an elastic structure such as a torsion spring, an elastic rope, or a rubber component.

[0046] When an electrical connection to the lightning arrester is required on the surface to be inspected, the probe assembly 10 can be placed against the surface of the lightning arrester and a certain pressure can be applied. When the end of the detection probe 11 contacts the surface of the lightning arrester, the detection probe 11 undergoes elastic compression deformation under pressure to achieve elastic contact with the surface to be inspected. After the probe assembly 10 separates from the lightning arrester, the detection probe 11 can return to its initial extension length.

[0047] The multiple detection probes 11 in the probe assembly 10 can adapt to different shapes of the surface to be inspected through their respective elastic compression deformation, thereby achieving stable electrical contact with various shapes of the surface to be inspected. At the same time, the probe assembly 10 can also absorb the small displacement caused by the shaking of the UAV through the expansion and contraction deformation of the detection probes 11, thereby improving the stability of the electrical connection and the detection accuracy.

[0048] In some embodiments, please refer to Figure 4The adaptive base 22 includes a first adaptive shell 221 and a second adaptive shell 222. A first adaptive element 23 is connected to the second adaptive shell 222, a limiting structure 22a is disposed on the first adaptive element 23, and a rod portion 111 is connected to the second adaptive shell 222. A detection circuit board 21 can be connected to the second adaptive shell 222, and the rod portion 111 is connected to the second adaptive shell 222 via the detection circuit board 21.

[0049] In some embodiments, please refer to Figure 4 The limiting structure 22a includes multiple connecting holes 220 formed on the first adaptive shell 221, and each detection probe 11 is movably connected to a connecting hole 220. Specifically, the detection probe 11 passes through the connecting hole 220, and the end of the detection probe 11 and the second adaptive shell 222 are located on opposite sides of the first adaptive shell 221, respectively. The detection probe 11 can slide axially or rotate around the axis in the connecting hole 220.

[0050] Optionally, the adaptive base 22 has a mounting cavity. The second adaptive shell 222 is connected to the first adaptive member 23 and together they enclose the mounting cavity. The connecting holes 220 connect the mounting cavity to the external space. The number of connecting holes 220 is the same as the number of detection probes 11, and they correspond one-to-one. The detection circuit board 21 is disposed in the mounting cavity, and the adaptive base 22 can protect the detection circuit board 21. The first adaptive shell 221 has a detection surface 2211, and the connecting holes 220 are formed on the detection surface 2211. The second adaptive shell 222 has a first connecting surface 2221, which is opposite to the detection surface 2211. The first driving member is connected to the first connecting surface 2221.

[0051] Optionally, the detection probe 11 can be fixedly and sealed to the wall of the connecting hole 220 via the rod 111 to achieve sealing of the mounting cavity and improve the waterproof performance of the self-adaptive seat 22.

[0052] Optionally, multiple detection probes 11 are arranged in an array. This allows the multiple detection probes 11 to be evenly distributed on the surface to be tested of the lightning arrester, achieving a stable electrical connection with the lightning arrester. The extension direction of the detection probes 11 can be perpendicular to the contact position on the surface to be tested, ensuring stable contact. The detection surface 2211 is also adapted to the surface to be tested of the lightning arrester, so the extension direction of the detection probes 11 is also perpendicular to the detection surface 2211, facilitating installation.

[0053] exist Figure 3 In the embodiment shown, the detection surface 2211 is planar, and the multiple detection probes 11 are parallel to each other to facilitate processing. The end face of the detection probe 11 can be spherical or curved to avoid scratching the surface of the lightning arrester to be inspected.

[0054] In some embodiments, please refer to Figure 3 and Figure 4 The adaptive mechanism 20 also includes at least one limiting block 25, which is connected to the adaptive seat 22 and protrudes from the detection surface 2211. The height of the limiting block 25 protruding from the detection surface 2211 is less than the height of the detection probe 11 protruding from the detection surface 2211. When the detection probe 11 contacts the surface to be tested of the lightning arrester, the detection probe 11 can be compressed until the limiting block 25 abuts against the lightning arrester. The limiting block 25 can limit the maximum compression of the detection probe 11 and prevent the detection circuit board 21 from being damaged when the compression of the detection probe 11 is too large.

[0055] The limiting block 25 can be connected to the detection surface 2211 to reduce the space occupied in the radial direction. The extension direction of the limiting block 25 is perpendicular to the detection surface 2211. The limiting block 25 and the adaptive seat 22 are integrally formed for easy processing.

[0056] In other embodiments, the limiting block 25 may also be connected to the peripheral side of the adaptive seat 22, or indirectly connected to the adaptive seat 22 through other structural components, which is not limited here.

[0057] Optionally, multiple limiting blocks 25 are provided, and the multiple limiting blocks 25 are arranged sequentially along the circumference of the probe assembly 10. In this way, multiple limiting blocks 25 can limit the compression of the detection probes 11 at multiple positions, avoiding the situation where the compression of individual detection probes 11 is too large. In the illustrated embodiment, there are three limiting blocks 25, and the three limiting blocks 25 can define a surface so that the compression of all detection probes 11 is limited. The three limiting blocks 25 can protrude from the detection surface 2211 at the same height to ensure that the maximum compression of all detection probes 11 is uniform.

[0058] In some embodiments, the limiting block 25 further includes a buffer pad for contacting the surface to be inspected. The buffer pad may be made of elastic materials such as rubber or foam to cushion the contact between the limiting block 25 and the lightning receiver, preventing the limiting block 25 from scratching the lightning receiver. Simultaneously, the buffer pad can increase the friction between the detection probe 11 and the lightning receiver, reducing the displacement of the detection probe 11 when it makes electrical contact with the lightning receiver.

[0059] In some embodiments, please refer to Figure 1The suspension detection device 100 also includes a connecting rod 30 and an electrical control box 40. The electrical control box 40 is used to connect the suspension device 200. The connecting rod 30 is connected between the adaptive mechanism 20 and the electrical control box 40, that is, the adaptive mechanism 20 is connected to one end of the connecting rod 30, and the electrical control box 40 is connected to the other end of the connecting rod 30. The adaptive mechanism 20 can change the state of the detection probe 11 relative to the connecting rod 30 through flexible deformation. The electrical control box 40 is communicatively connected to the detection circuit board 21 and is used to control the detection probe 11 to perform detection. The above-mentioned communication connection can be a wire connection, a flexible circuit board connection, or a wireless connection.

[0060] The connecting rod 30 is a high-strength rod-shaped structure that connects the probe assembly 10 to the suspension device 200 and maintains a preset distance between them. When the probe assembly 10 moves with the suspension device 200 to the vicinity of the lightning arrester and makes electrical contact with it, the suspension device 200 is effectively prevented from touching the lightning arrester. Furthermore, the control box 40 is also communicatively connected to the suspension device 200, and can control the flight position and angle of the suspension device 200.

[0061] Optionally, the electrical control box 40 has a grounding connector 41. When it is necessary to perform grounding test on the lightning arrester, a grounding wire can be electrically connected to the grounding connector 41 to achieve grounding of the lightning arrester to the ground through the grounding wire.

[0062] In some embodiments, please refer to Figure 1 The suspension detection device 100 also includes a vision module 50 connected to the connecting rod 30. The vision module 50 is used to acquire image information near the probe assembly 10. The vision module 50 can also be connected to the electrical control box 40, and the electrical control box 40 can control the flight position and angle of the suspension device 200 and the detection process of the probe assembly 10 according to the image information acquired by the vision module 50.

[0063] In some embodiments, please refer to Figure 1 and Figure 2The suspension detection device 100 also includes an adjustment mechanism 60, which is connected between the electrical control box 40 and the suspension device 200. Specifically, the electrical control box 40 is connected to the suspension device 200 via the adjustment mechanism 60. The adjustment mechanism 60 is used to adjust the position and orientation of the connecting rod 30. The position and orientation of the connecting rod 30 includes the angle of the connecting rod 30 relative to the suspension device 200 and the extension / retraction length of the connecting rod 30. The connecting rod 30 may also have several bending points in its middle, and the position and orientation of the connecting rod 30 may also include the bending angle of the connecting rod 30 at each bending point. The adjustment mechanism 60 is also communicatively connected to the electrical control box 40, which can control the adjustment mechanism 60 to adjust the position and orientation of the connecting rod 30. The adjustment mechanism 60 can adjust the position and orientation of the connecting rod 30 through its own shape changes or transmission structure.

[0064] In some embodiments, please refer to Figure 4 The adaptive mechanism 20 also includes a plurality of detection elements 26, each detection element 26 being used to detect the pressure parameters and / or pose parameters of at least one first adaptive element 23.

[0065] Each detection element 26 can also be one of a pressure sensor, an angle sensor, and a displacement sensor. The control box 40 can obtain the state and force of the probe assembly 10 based on the changes in the pressure parameters and / or posture parameters of the first adaptive element 23 detected by the multiple detection elements 26, thereby controlling the adjustment mechanism 60 to adjust the posture of the connecting rod 30 so that the probe assembly 10 and the lightning arrester can achieve a more stable electrical connection.

[0066] Optionally, the number of detection elements 26 is equal to the number of first adaptive elements 23, and each detection element 26 corresponds one-to-one with each first adaptive element 23. Each detection element 26 is used to detect the pressure parameters and / or pose parameters of a first adaptive element 23.

[0067] exist Figure 3 In the illustrated embodiment, three first adaptive elements 23 are provided, and the three first adaptive elements 23 are arranged at equal intervals around the central axis of the adaptive seat 22 to form a virtual equilateral triangle. By providing three first adaptive elements 23 arranged in an equilateral triangle, the state feedback modeling process of the probe assembly 10 can be simplified and the cost reduced. Three detection elements 26 are provided, and one detection element 26 is connected to each of the first adaptive elements 23. The central axis of the adaptive seat 22 passes through the center point of the detection surface 2211 and is perpendicular to the detection surface 2211.

[0068] In some embodiments, please refer to Figure 4The fixing base 24 includes a first fixing part 241 and a second fixing part 242 connected together. The first fixing part 241 has a second connecting surface 2411. The connecting rod 30 is connected to the second fixing part 242. The first end wall of the first adaptive member 23 is connected to the first connecting surface 2421, and the second end wall is connected to the second connecting surface 2411. The first fixing part 241 and the second fixing part 242 together form a receiving cavity, and the detection member 26 is disposed in the receiving cavity. In this way, the adaptive fixing base 24 can protect the detection member 26, and the first fixing plate and the second fixing plate realize the fixed connection of the first adaptive member 23.

[0069] It should be noted that the first adaptive member 23 may also omit the first end wall and the second end wall, and only have the third end wall 231. The second adaptive shell 222, the second fixing part 242 and the third end wall 231 are used together to form a closed cavity. No restrictions are imposed here.

[0070] Optionally, the adaptive mechanism 20 also includes a control circuit board 27 disposed within the mounting cavity. All detection elements 26 are electrically connected to the control circuit board 27. The control circuit board 27 can process the detection results of the detection elements 26 and send the processing results to the electrical control box 40. The housing cavity can be a sealed cavity to achieve waterproof and dustproof protection for the control circuit board 27 and the detection elements 26.

[0071] In some embodiments, please refer to Figure 2 The adjustment mechanism 60 includes at least one adaptive adjustment element 61, which may have the same or similar structure as the first adaptive element 23. The two ends of the adaptive adjustment element 61 are respectively connected to the electrical control box 40 and the suspension device 200.

[0072] Optionally, an adaptive adjuster 61 is provided, which is threaded tubular in shape to facilitate its own telescopic and / or torsional deformation to change the position of the connecting rod 30.

[0073] In some embodiments, the suspension detection device further includes a controller connected to the suspension device 200. The controller is electrically connected to the detection element 26 and can change the position and acceleration of the suspension device 200 based on the feedback from the detection element 26, thereby adjusting the orientation of the detection surface 2211 and the pressure applied to the lightning arrester.

[0074] Optionally, the hovering device 200 can be a generalized aircraft, not limited to drones.
